The short answer
The Fungabeam Pen is a twist-and-brush nail care pen for discolored, thickened or brittle nails. Each 3 mL pen holds a plant-based formula with tea tree leaf oil, lemon juice, aloe and vitamin E that you paint directly onto the nail and along its edges, twice a day. The maker says some users notice the appearance improving in 5 to 7 days, with fuller changes as the nail grows out. In 2026 it costs $13.99–$19.99 per pen on the official site, ships to the US and Canada, and comes with a 30-day money-back guarantee.
Everyone who has dealt with a yellow, thick or crumbly toenail knows the real problem. It is not finding something to put on it. It is keeping it up. The cream that gets rubbed over the whole toe, the soak that needs a towel and twenty minutes, the bottle with the dropper that ends up in the back of the cabinet after a week.
The Fungabeam Pen was designed around that problem: a precise, clean, pocket-size routine that takes seconds, so the twice-a-day habit actually survives contact with real life.
*Maker’s figure for appearance; individual results vary. Nails grow slowly, so fuller changes take weeks.
How the Fungabeam Pen works: three simple steps
There is nothing to mix, measure or rinse. If you can use a highlighter, you can use this:
- Twist the baseA twist releases the formula into the soft brush tip, in a controlled amount, ready to apply.
- Brush it onto the nailPaint the surface of the affected nail, run the brush along the edges and under the free edge. The formula stays where you put it instead of spreading over the skin.
- Repeat morning and nightIt absorbs quickly with no greasy residue, so there is nothing to wipe. Twice a day, every day, is the whole routine.
Put the formula where the problem actually is
Nail fungus doesn’t sit on top of the nail. It lives under and inside it, which is why creams spread over the toe mostly end up on the skin. The brush tip lets you work the formula into the edges and under the free edge of the nail — the places discoloration starts — and nowhere else. The maker’s wording is careful and we think fair: it is designed to target nail fungus at the source and support healthier nail regrowth, improving the appearance of discolored, thickened nails with consistent use.
Why people choose the Fungabeam Pen
Built for real life, not just the bathroom cabinet
The pen format is what makes the twice-a-day rule realistic. It travels, it doesn’t leak, and it takes about as long as brushing your teeth:
Gentle enough for twice-daily use
The formula is plant-based — the box lists tea tree leaf oil, lemon juice and aloe leaf juice with tocopherol (vitamin E) — and the maker positions it as a more comfortable option for repeated daily use than harsher chemical treatments, including on nails that are already thick and damaged. It can be used on more than one nail; just make sure each nail is clean before you brush it on.

What to expect in the first weeks
Set your expectations like a nail, not like a cream. A nail grows slowly, so a clearer-looking nail is something you watch come in from the base over weeks, not something that happens overnight. The maker says some users notice the appearance improving in as little as 5 to 7 days, with more visible changes as you keep going. The practical takeaway: one pen is a test, three pens is a real routine, and six pens is the full-course option for more than one nail or for a nail that is already thick and damaged. (We wrote up a realistic week-by-week timeline in how long it takes for a toenail to grow out.)

Frequently asked questions
What is the Fungabeam Pen?
The Fungabeam Pen is a nail care pen for discolored, thickened or brittle toenails and fingernails. You twist the base and a plant-based formula — the box lists tea tree leaf oil, lemon juice, aloe leaf juice and vitamin E — flows into a soft brush tip that you paint directly onto the nail and along its edges. Each pen holds 3 mL (0.1 fl oz).
How do I use it?
Twist the base to release the formula into the brush, brush it onto the clean nail and along the edges, and repeat morning and night. The maker recommends twice-daily use and says it can be applied to more than one nail.
How soon will I notice a difference?
The maker says some users notice the appearance improving in as little as 5 to 7 days, with more visible changes as use continues. Because nails grow slowly, the clearer nail comes in gradually from the base over weeks, so plan on a daily routine rather than a quick fix.
